Actor Matthew Broderick turned up at City Hall today to add star power to opponents of NYU’s hard-fought plan to expand its campus in Greenwich Village.

“They might need to expand, but they certainly don’t need to destroy the Village,” Broderick told reporters at the packed hearing before the City Council, which has to approve the two-million-square foot expansion.

“There’s already so little open space and open air…I used to play in the area when I was a child, so it’s very important to me growing up.”

Broderick, who starred in the 1986 hit movie “Ferris Bueller’s Day Off” and is now appearing on Broadway in “Nice Work if You Can Get It,” seemed surprised that his appearance caused so much commotion.

“I’m on TV now,” he marveled while being questioned by a cluster of reporters.

“For me, park land is extremely important,” he explained. “There’s not that much of it. I’ve watched so much of it disappear, so many small, nice, beautiful buildings being knocked over for huge dorms. I think it’s gone too far and it’s really hurting the Village.”

Broderick said he hasn’t discussed his views with NYU officials.

“I don’t talk to them that much,” he said. “I go about my business, they go about theirs.”

The City Planning Commission and the Manhattan Borough President’s office have already approved NYU’s plan, making the Council the final hurdle.

City Councilwoman Margaret Chin (D-Manhattan), whose district includes the Village, made it clear she wouldn’t go along without modifications.

“I strongly believe that this plan is unacceptable in its current form,” said Chin. “The amount of density that NYU has proposed is out of scale with the surrounding community.”

But Chin also indicated she wasn’t about to block the entire project, which has been five years in the making.

“I want to acknowledge that NYU is an important institution and this proposal will bring thousands of jobs and new opportunities to our city,” she said. “It is important for our city — and for the Village– that NYU remains competitive and has the space to grow.”
